PEPmodel

Welcome to the PEP demonstration code.

Please see the documentation in src/classes/doc or the source code in src/classes/model. The source has been HTMLized under doc/model whit a java app called JavaExpander which I hope to find time to finish and give out.

Purpose

The PEPmodel package was designed for:

• proof of concept
- prove that PEP is both useful and implementable
• API testbed
- implement different PEP extensions and learn what PEP library interface is needed to support them
• implementation suggestions
- provide a starting point for PEP implementation in browsers and servers

Obtaining

The PEPmodel package is distributed in zipped and gzipped formats. The source tree may be browsed in java source file form or html form.

Building

Because the Makefiles change directory, "." is not a sufficient CLASSPATH. Instead, you must specify a full path up to src/classes. You must also specify where the makefiles directory is. For instance, if you have copied PEPmodel into /usr/local/src/PEPmodel, you may go to /usr/local/src/PEPmodel/src/classes and type:

CLASSPATH=/usr/local/src/PEPmodel/src/classes MAKEDIR=/usr/local/src/PEPmodel/makefiles make

This will also require to have the java compiler, javac, in your classpath.

Running
Of course, java renders all of this moot as the distribution binaries may be run on any
JVM. You need to set your CLASSPATH. If you installed this package in
/usr/local/src, your CLASSPATH will point to
/usr/local/src/PEPmodel/src/classes. With a Sun JVM, you may hae to
add classes.zip to the CLASSPATH, eg

export CLASSPATH=/usr/local/src/PEPmodel/src/classes:/usr/java/lib/classes.zip
On windows, the CLASSPATH separator is a ';' rathern than a ':':

set CLASSPATH c:\PEPmodel\src\classes;\Java\lib\CLASSES.ZIP

Here's how you run the Server:
java w3c.model.tools.basicweb.Server -port 8888

You will see something like: 
<!- server root
"/afs/w3.org/pub/WWW/Protocols/PEP/PEPmodel/src/classes/">
 and it will
sit there until you give it a reuqest from the client:
java w3c.model.tools.basicweb.Client http://localhost:8888/escaped/doc/Overview.html

You should see a status line from server like this:
<!- reading "HTTP/1.1 200 OK" ->
